[TowerTalk] vertical antenna feedpoint

[WW3S]

what should the impedance be? I thought I read somewhere ideally around 
36-40 ohms...testing my new 30m vertical showed around 75 ohms, and 
mostly flat for 2 meg or more, which I seem to recall is really not the 
best...am I correct that while a wide bandwidth seems good, it really 
isnt, I think maybe its telling me the radial system needs improved?
